If your mail server responds "appropriately" to the SMTP RFC821 dialog, then LISTSERV sites that have generated e-mail to you should automatically delete those users. Otherwise, the site's NAD can issue a DEL * userid@site There might be a magic-cookie dialogue that takes place though depending on the lists' level of security (* VALIDATE=). A site's NAD can be defined in the BITEARN NODES db, or POSTMASTER userid (as well as one or two others). There may be a non-BITNET file that defines who they are (SERVICE?). /Pete Weiss
